Problems solved by technology

[0003] First, after the above materials are used, there are many residues left on the road surface or on the test pieces, which are not easy to clean up;
[0004] Second, these materials must be new and cannot be reused. When there are many test pieces or many on-site inspection points, the material consumption will be quite large;
[0005] Third, these materials cannot be stored for a long time, and they must be repurchased before each test, which is not convenient and economical; because the above materials do not have the function of locking water, the moisture will evaporate during storage and the materials will lose water and dry out, thus Can not maintain plasticity for a long time

Embodiment 1

[0025] This embodiment provides a sealing material for the asphalt mixture water seepage test, which includes 70 parts of waterproof putty, 15 parts of engine oil and 15 parts of diesel oil, and is prepared into required doses according to site requirements. First, add 70 parts of waterproof putty into the mixer, and then add 15 parts of engine oil and 5 parts of diesel oil into the mixer. Stir for 0.5 h at room temperature, take out the stirred mixture, knead the mixture into a ball, and store in a sealed bag. The mixture of engine oil and diesel can form an anti-stick oil film layer between the sealing material and the asphalt mixture pavement or test piece, which can be completely recovered after the sealing test, and the loss rate is less than 1%, and there is no need to repair the asphalt mixture pavement or test piece to clean up. In addition, the waterproof putty itself has anti-corrosion and sealing properties. In the kneaded waterproof putty, it can effectively lock ...

Embodiment 2

[0027] This embodiment provides a sealing material for the asphalt mixture water seepage test, which includes 70 parts of waterproof putty, 20 parts of engine oil and 10 parts of diesel oil, and is prepared into required doses according to site requirements. First, add 70 parts of waterproof putty into the mixer, and then add 20 parts of engine oil and 10 parts of diesel oil into the mixer. Stir for 1 hour at room temperature, take out the stirred mixture, knead the mixture into a ball, and store in a sealed bag.

[0028] To sum up, the present invention utilizes the characteristic of high water absorption rate of the putty material itself, adds an inert oil component material, and after fully mixing with the main material, a microscopic film is formed on the surface of the mixture, so that the moisture inside the mixture is sealed and difficult to volatilize, so it can be kept sealed for a long time Material plasticity. At the same time, the inert oil component material has ...

Abstract

The invention discloses a sealing material for an asphalt mixture infiltration test. The sealing material comprises the following components in parts by weight: 50-90 parts of waterproof putty, 1-40 parts of engine oil and 1-20 parts of diesel oil. The invention furthermore discloses a preparation method of the sealing material for the asphalt mixture infiltration test. The method comprises the following steps: adding 50-90 parts of waterproof putty into a stirrer, and sequentially adding 1-40 parts of engine oil and 1-20 parts of diesel oil into the stirrer; and performing stirring for 0.5-1hour at a normal temperature, taking out the stirred mixture, kneading the mixture into balls, and packaging and preserving the mixture by a sealing bag. According to the scheme, the sealing materialdisclosed by the invention has the advantages of being reliable in seal, cleaning-free, recyclable and the like, and has extremely high practical values and popularization values in the technical field of the asphalt mixture infiltration test.

Description

technical field [0001] The invention relates to the technical field of asphalt mixture water seepage test, in particular to a sealing material and a preparation method thereof for the asphalt mixture water seepage test. Background technique [0002] In the rolled asphalt mixture pavement or test piece, in order to obtain parameters such as the density, relative density, and void ratio of the asphalt mixture, according to the provisions of the "Test Regulations for Asphalt and Asphalt Mixtures in Highway Engineering", the rolling Formed asphalt mixture pavement or specimens are subjected to water permeability test. Since there is no equipment or components on the surface of the rolled asphalt mixture pavement or the test piece, during the water permeability test, the test water will flow unimpeded outward along the test point, which causes the problem of inaccurate test. In the prior art, waterproof putty, putty or plasticine are mainly used as shielding parts, however, the ...
